Parameters
- pSrc
- Pointer to the ROI in the pixel-order source image. Array of pointers to the ROI in each plane of the planar source image.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image. Array of distance values for the source image planes.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination image.
- roiSize
- Size of the source and destination ROI in pixels; its width should be multiple of 2.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function converts
4:2:2
YCbCr
source image pSrc
to the 4:2:2 CbYCr
two-channel image pDst
that has the following
sequence of samples: Cb0
, Y0
, Cr0
, Y1
, Cb1
, Y2
, Cr1
, Y3
, Cb3
, ... (see Table “Pixel-Order Image Formats”
). The source image can be either
two-channel or three-plane (see Table “Pixel-Order Image Formats”
and Table “Planar
Image Formats”
).Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if any of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSize.widthof the first plane is less than 2, orroiSize.heightis less than or equal to zero.
